    [0001] The invention relates to a transmitter for a gearbox, in particular a motor vehicle, to an assembly comprising a transmitter, a transmission shaft and a gear wheel, and transmission. a transmitter, a transmission shaft and a gear wheel, and a transmission. In gearboxes as used in particular in motor vehicles, the synchronization assembly is used to establish a rotational solidarity connection between a transmission shaft and a gear wheel or a gear wheel arranged on the gear shaft. transmission as a crazy gear. In a first step of the gearshift process, the synchronization assembly ensures that the speed of rotation of the gear gear to be switched is adapted to the rotational speed of the transmission shaft. In a second step, a rotationally solid connection is then established between the transmission shaft and the gear wheel. The appropriate speed is then passed. Synchronization assemblies are generally known which have as essential components a synchronizing hub, pressure pieces received therein, synchronizing rings and a sliding sleeve. Upon actuation of the sliding sleeve, one of the synchronizing rings is pushed by means of the pressure parts and / or the locking chamfers against a friction surface associated with the speed gear to be switched. When the speed of rotation of the speed gear is synchronized with the rotational speed of the transmission shaft, the sliding sleeve can be fully switched to engage in a toothing associated with the gear wheel. A rotationally fixed connection of the synchronization hub to the gear wheel is thus achieved. Synchronization assemblies are also known which instead of a synchronizing hub use a so-called transmitter which in general terms collects the function of the synchronizing hub, the pressure pieces and the sliding sleeve. The basic structure of a transmission including such a timing assembly is explained below with the aid of FIGS. 1 to 8. The transmission contains a transmission shaft 10 on which two speed gears 12, 14 are arranged. Both gear gears 12, 14 are in the form of idle gears and can therefore rotate relative to the drive shaft. A speed gear toothing 16 is integrally associated in rotation with each gear gear 12, 14. This gear is provided in the form of internal toothing on a separate component 17 which is integrally connected to the gear wheel 12, 14 correspondent. A transmitter 18 formed here by a transmitting disc 20 and two clutch disks 22 is arranged between the two speed gears 12, 14. The two clutch disks 22 are arranged on either side of the transmitting disc 20 and have an external toothing 24 of clutch disc and an internal toothing 26 of clutch disc. The external toothing 24 is made to be complementary to the toothing 16 of the speed gear, and the internal toothing 26 is in engagement with a toothing 28 of the transmission shaft. The clutch disks 22 are thus coupled to the transmission shaft 10 integrally rotated in the peripheral direction, but may however be displaced in the axial direction on the transmission shaft. A respective synchronizing ring 30 is arranged on either side of the transmitting disk 20 and can cooperate with a friction surface 32 which is associated with the corresponding speed gear 12 or 14, respectively. The two timing rings have a plurality of drive posts 34 which extend into recesses 36 in the transmitting disc 20, as well as two connecting tabs 38 which are diametrically opposed to each other and extend through connection ports 40 in the transmitter disk 20 (see in particular FIG. 3). The connecting tabs 38 serve to couple the two synchronizing rings to one another in the axial direction. In the coupled state (see FIG. 4), the free ends of the driving pins 34 of the two synchronizing rings 30 are closely opposed. A pressure piece 42 (see in particular FIGS. 5 and 6) which is respectively biased radially outwards by a spring 44 is arranged in each of the recesses 36. A pre-synchronization face 46 3032756 is formed in FIG. the radially outer end of each pressure piece and rests on pre-synchronization chamfers 48 formed at the free ends of the driving pins 34 on the radially inner side (see FIG. 7). The pre-synchronization chamfers 48 of the driving lugs 34 opposite each other are oriented so as to form a V with a large opening angle whose tip is directed radially outwards. Blocking surfaces 50 are formed on the drive posts 34 which, viewed in the peripheral direction, are opposite to the edges of the recess 36 while being obliquely oriented. The locking surfaces 50 here also form at the opposite drive lugs 34 a V, the tips of the two Vs of the opposing drive lugs facing each other towards the center of the recess 36. The synchronization assembly described operates as follows: When a speed is to be passed, for example that which contains the speed gear 14, the transmitter 18 is moved on the transmission shaft 10 in the direction of the arrow P of Figure 1 in the axial direction by means of a gearbox fork (not shown). In a first step called pre-synchronization, the two synchronizing rings 30 are driven to the left by the pressure pieces 42, more precisely by the pre-synchronization surface 46 of the pressure piece 42 which engages on the left pre-synchronization chamfer 48 of the left synchronizing ring 30, so that the synchronizing ring 30 comes into frictional engagement with the friction surface 32. Normally, the rotational speed of the transmission shaft 10 does not change. does not correspond to the rotational speed of the speed gears so that there is a difference in rotation speeds between the synchronizing ring 30 and the friction surface 32. This causes the synchronization ring to be driven in the direction of rotation. device (see arrow U in Figure 8), whereby the blocking surface 50 is supported on the upper edge in Figure 8, the recess 36. Because of the oblique orientation of the blocking surface 50, a force component is thus generated, which prevents a displacement of the transmitting disk 20 relative to the drive tébbn 34. As long as there is a difference in rotational speeds, the torque of The resultant friction results in the locking surface 50 being pushed against the edge of the recess 36. The synchronizing ring then bears against the friction surface 32 and can no longer be moved in the axial direction. Only when the difference in rotation speeds is lowered does the locking force exerted by the blocking surface 50 is reduced so that the edge of the recess 36 of the transmitting disk 20 can move the blocking surface 50 into the peripheral direction against the direction of arrow U due to its oblique orientation, which allows switching of the transmitter. The pressure pieces 42 are at the same time damped down against the effect of the spring 44 by the pre-synchronization chamfers 48 inclined obliquely. The transmitter can thus be moved axially until the external toothing 24 of the clutch disc 22 engages in the gearing pinion gearing 16 associated with the gear wheel 14. A link secured in rotation between the gear shaft transmission 10 and the gear wheel 14 to switch is established.
    [0002] Unlike the embodiment shown, the presence of a precisely defined bevel as to length and angle on a single component, for example, is sufficient. A complementary bevel on the antagonistic component, the transmitter for example, is advantageous for a flat support against the blocking bevels. One of the two bevels could in principle also be omitted or be made domed, for example. To unlock the engaged speed, the transmitter 18 is again moved in the opposite direction in its middle position, whereby the two synchronizing rings 30 can also be moved to a middle position again. In this position, the frictional engagement with the friction surfaces 32 is suppressed. The object of the invention is to develop the known synchronization sets so as to obtain a more compact structure. To achieve this goal, a transmitter is provided according to the invention for producing a link secured in rotation between a transmission shaft and a gear wheel mounted to rotate about it, having a transmitting disk and a disk clutch which is associated with the transmitting disc and has an external clutch disc toothing, characterized in that the transmitting disc is provided with the outer side of a transmitter toothing. The invention is based on the fundamental idea of making one of the teeth 3032756 predicted until now on the clutch disk directly on the transmitter disk. The transmitter toothing is thus arranged outside the synchronizing rings, which allows a shorter mounting space in the axial direction. According to one embodiment of the invention, it is provided that the transmitter toothing is arranged on the outer periphery of the transmitting disk. This results in a structure as short as possible in the axial direction, since seen in the axial direction, the transmitter toothing coincides with the transmitter disk. It may further be provided that two synchronizing rings are mounted on the transmitting disk. The mounting of the synchronizing rings and the configuration of the transmitter disk required for this purpose are not modified so that compared to the structure of the transmitter known so far, we obtain a lower construction effort. It is preferably provided that an actuating element is attached to the transmitter disk in the axial direction. The actuating element makes it possible to shift the transmitter disk in the axial direction without having to engage the outer periphery of the transmitting disk as before. According to one embodiment, it is provided that the clutch teeth are provided on a clutch disc associated with the transmitting disc. This allows the transmitter disk to be constructed as a planar component, particularly as a sheet metal component, since the clutch gear is provided on a separate component. It is preferably provided that the clutch disc is arranged on a front face of the transmitting disc and is connected thereto in the axial direction. It is not necessary to connect the clutch disc integrally in rotation to the transmitting disc such that the rotational torque between the transmission shaft and the switched speed gear is transmitted through the disc. clutch and transmitter disk. It is sufficient to connect the clutch disc to the transmitting disc so that the clutch disc 30 follows the axial movements of the transmitting disc. The torque can be directly transmitted by the clutch teeth to the drive shaft by equipping the clutch disc on the inside of a toothing that engages in a complementary toothing of the transmission shaft.
    [0003] In order to achieve the aim mentioned above, an assembly comprising a transmission shaft, at least one gear wheel mounted to rotate about it, and a transmitter of the type mentioned in the introduction, is also provided according to the invention. the gear wheel being provided with a gear gear toothing with which the gear teeth can be brought into engagement. In addition, two speed gears can be coupled to the gearshift shaft by means of the transmitter according to the invention, the torque being transmitted from the drive shaft to one of the gear gears via of the clutch disc, and to the other gear gear via the transmitting disc. This makes it possible to arrange your gear gears closer to each other in the axial direction. According to one embodiment of the invention, it is provided that an actuating element which extends in the axial direction from the transmitting disk engages on the transmitting disk. This actuating element leaves the mounting space around the free transmitter gear so that it is not necessary to account for a mounting space for actuating the transmitter disk. The actuating element can extend around the transmission shaft in the manner of a socket. This results in a low construction effort.
    [0004] Alternatively, it can be provided that the actuating element is arranged inside the transmission shaft. This makes it possible to actuate the transmitter even when it is not well accessible from the outside in the axial direction, for example because it is arranged between several pairs of gear gears. It is then preferably provided that the actuating element is coupled to the transmitter disk through an orifice in the transmission shaft. A small window is sufficient for this purpose, which does not significantly weaken the drive shaft. According to an embodiment of the invention, it is provided that the speed gear is provided with a gear gear toothing with which the gearing of the transmitter can be brought into engagement. This results in a direct torque transmission of the transmitting disk to the corresponding gear wheel.
    [0005] 3032756 Sprocket gear teeth can be made in one piece with the gear wheel. Costs for mounting a separate component are avoided. Alternatively it can be provided that the gear pinion gear is provided on the inner periphery of a toothed gear pinion disc which is connected to the gear pinion in rotationally integral manner. This makes it possible to manufacture the gear pinion gear on a sheet metal component that can be produced at little cost, for example by cutting, which is then connected to the gear wheel (where appropriate after a curing procedure).
    [0006] According to one embodiment, the gear wheel is provided with a friction surface capable of cooperating with a synchronizing ring. This makes it possible to keep as much as possible the structure known until now so that only small modifications are necessary. The friction surface is preferably provided directly on the gear wheel 15. This reduces the number of all necessary components. The friction surface can be oriented radially outwards. It can also be provided that the friction surface is oriented radially inwards. This can be optimally chosen depending on the respective marginal conditions.
    [0007] According to one embodiment of the invention it is provided that the friction surface is arranged radially inside the gear pinion gear. It. results in a compact structure in the axial direction. To achieve the above-mentioned purpose, a transmission comprising an assembly of the type mentioned above is also provided according to the invention, the transmission having a housing provided with a locking toothing with which the transmitter toothing can be brought into engagement. In this embodiment, the transmitter disk is used for the establishment of a fixed connection in rotation between the transmission shaft and the transmission housing so that the transmission is for example locked in a parking position. Unlike the embodiments used for synchronization, a synchronizing ring on the side of the transmitting disk on which the engagement with the transmission box is made is not necessary for the parking brake function.
    [0008] The invention will be described in the following using various embodiments shown in the accompanying drawings. These show: - Figure 1 in section and schematically a synchronization assembly known from the state of the art, - Figure 2 in an exploded view of the synchronization assembly of Figure 1, - Figure 3 in a perspective view a transmitter with synchronizing rings mounted thereon; - Fig. 4 in a perspective view the synchronizing rings 10 of Fig. 3; Fig. 5 in a perspective view the transmitter of Fig. 3; 6 is a section along plane VI-VI of FIG. 1, FIG. 7 is a section along plane VII of FIG. 6, FIG. 8 is a section along plane VIII of FIG. Figure 9 in section and schematically a portion of a transmission according to a first embodiment of the invention, and Figure 10 in a view corresponding to that of Figure 9 a second embodiment of the invention. A first embodiment of a transmitter according to the invention is now described with reference to FIG. 9. The same reference numerals are used for the already known components of FIGS. 1 to 8. On this point, we refer to FIGS. explanations above. The main difference between the assembly as shown in FIG. 9 and the known assembly of FIGS. 1 to 8 consists in the transmission of the torque 25 between the transmitting disc 20 and one of the speed gears (here the pinion 12) is not effected via a clutch disc with a clutch disk gear, but via a transmitter toothing 25 made on the transmitting disc 20.
    [0009] The transmitter gear 25 is here provided directly on the transmitting disk 20, more precisely in the form of teeth on the outer periphery of the transmitting disk. The transmitter disc 20 may be manufactured with the transmitter toothing 5 as a planar component, for example from a sheet which is cut. Another difference between the transmitter disk 20 used in the embodiment according to FIG. 9 and the known transmitter disk of FIGS. 1 to 8 is that in the embodiment according to FIG. 9, the transmitter disk 10 is provided with an internal toothing 21 of transmitter disk. The latter engages as the internal toothing 26 of the clutch disk integrally in rotation but axially displaceable in the toothing 28 of the transmission shaft. Gear gear toothing 60 is provided on the gear gear 12, with which the gear teeth 25 can be brought into engagement. Here, the pinion gear 60 is here provided on a toothed gear disk 62, which is connected in rotation with the gear pinion 12, for example by welding. Gear toothed disc 62 may be a sheet-cut component which, if desired, is cured at least in the area of gear pinion gear 60. It is alternatively also possible to make the gear gear teeth 60 in one piece with the gear wheel 12. In the embodiment shown in FIG. 9, the transmitting disk 25 also carries two synchronizing rings 30. 31. Unlike the embodiment shown in FIGS. 1 to 8, however, the two synchronizing rings have a different geometry. The synchronizing ring 30 tapers slightly outwardly from the transmitter disk 20 so that it can be threaded onto the outwardly facing conical friction surface 32 which is provided on the component 17. However, the synchronizing ring 31 tapers in the axial direction away from the transmitting disc 20 so that it can be threaded into a friction surface 33 which is conically formed and radially inwardly oriented and is made on the gear wheel 12. The friction surface 33 is here formed as a stage on the speed gear 12, that is to say in one piece with it. It is basically also possible to make a separate component on the gear wheel 12, on which the friction surface is then provided. An actuating element 70 by means of which the transmitting disc 20 can be urged axially on the transmission shaft 10 is provided on the transmitting disk 20. The actuating element 70 serves the function of a fork. which in the embodiment according to Figures 1 to 8 engages on the outer face of the transmitter disc 20 to move the latter in the axial direction. In the embodiment according to FIG. 9, the actuating element 70 is made in the manner of a bushing which surrounds the transmission shaft 10.
    [0010] The actuating element 70 then engages on the transmitting disk 20 by a flange 72 arranged at the location where the second clutch disc 22 is arranged in the embodiment according to FIGS. 1 to 8. relating to the operation during synchronization and shifting, the embodiment according to FIG. 9 is not distinguished from the embodiment according to FIGS. 1 to 8. When the transmitting disk 20 is actuated from a middle position in one direction (see arrow S), the two synchronizing rings 30, 31 are driven in the corresponding direction The synchronizing ring arranged "at the front" in the switching direction comes into engagement with the friction surface 32 or 33 respectively, and the synchronization process begins. When the rotational speeds of the transmission shaft and the corresponding speed gear 12 or 14 are harmonized, the transmitting disc 20 can be fully switched so that the torque is transmitted from the transmission shaft 10 to the gear wheel. speed 12 via the internal toothing 21 of the transmitter disk, 30 of the transmitter disk 20, of the transmitter toothing 25 and of the gear pinion 60 when the gear wheel 12 is switched, or so that in the case of the speed gear 14, the torque is transmitted by the internal toothing 26 of the clutch disk via the clutch disk 3032756 22 and the clutch gear 24 to the component 17, and since the latter to the speed gear 14. The advantage of the embodiment according to FIG. 9 with respect to the embodiment according to FIGS. 1 to 8 consists in particular in that a more compact structure in the axial direction ial is possible. As can be seen in FIG. 9, the teeth of the speed gear 12 can be arranged in the axial direction very close to the transmitting disc 20. In the embodiment shown, the gearing gearing of the gear wheel 12 protrudes from the disc 20. This is possible because with respect to the embodiment according to FIGS. 1 to 8, the arrangement of the gear gear toothing and the friction surface on the gear gear is exchanged. The friction surface 33 on the speed gear 12 is arranged radially inside the gear pinion 60, and the gear pinion 60 is arranged closer to the transmitting disc than the friction surface 33.
    [0011] It is therefore not necessarily necessary to connect the actuating element 70 laterally inside the synchronizing rings 30, 31. It could also be provided to provide radially outside the synchronizing rings 30, 31 on the speed gear 14 side an insert on the transmitting disc 20 by means of which a groove or circumferential edge 20 is formed adjacent to the transmitter toothing, so that a gear slider or fork can engage in it. Figure 10 shows another embodiment. The same reference numerals are used for the known components of the previous embodiments, and here reference is made to the explanations above.
    [0012] The difference between the embodiment according to FIG. 10 and the embodiment according to FIG. 9 is that in the embodiment of FIG. 10, the transmitter switches a single gear wheel (here the gear wheel 14 ). When the transmitter disk 20 is switched to the right from the middle position shown in FIG. 10, it reaches engagement 30 with a locking toothing 80 provided on a housing 82 of the transmission in which the transmission shaft 10 is mounted. The locking toothing 80 is here made in one piece with the housing 82. It is also possible to provide the locking toothing 80, such as the toothing 3032756 12 60 of the speed gear in the embodiment according to FIG. 9, on a separate component which is then mounted on the housing 82. Another difference between the embodiment of FIG. 10 and the embodiment of FIG. 9 is that in the embodiment of FIG. the actuating element 70 is arranged inside the transmission shaft 10. It is provided with an actuating extension 74 which extends axially outwards through an orifice 76 in the drive shaft. transmission 10 and which is connected to the transmitter disk 20. In the embodiment according to Figure 10, a friction surface 32 is provided on the housing 82, which is oriented radially outwardly in the same manner as the surface of friction 32 on the 17. It is thus possible to arrange two synchronization rings 30 of identical geometry on the transmitting disk. When in the embodiment according to FIG. 10, the transmitting disc 20 is moved to the left from the middle position shown, a speed change is made in a known manner by means of the speed gear 14. But if the disc Transmitter 20 is moved to the right, a kind of synchronization process is performed leading to the rotation speed of the transmission shaft 10 being brought to zero until the transmitter disk 20 can finally be switched. . The transmission shaft 10 is thus secured to rotate in the housing 82 by means of the toothing 28 of the transmission shaft, the internal toothing 21 of the transmitter disk, the toothing 25 of the transmitter and the locking toothing 80 According to a development not shown, the actuating element 70 arranged inside the transmission shaft can also be used in the embodiment of FIG. 9 in which two gear gears can be switched by means of of the transmitting disc. The known bushing-shaped actuating element 70 of the embodiment of FIG. 9 may, conversely, be used in the embodiment of FIG. 10 in which the transmitting disk 30 can be brought into engagement with the toothing. In the embodiment according to FIG. 9, it is furthermore possible to use a friction surface 32 oriented radially outwards as used in the embodiment of FIG. 10. Conversely, it is possible to use a friction surface 33 oriented radially towards the inside of the housing side 82 in the embodiment according to FIG. 10, as known from the embodiment according to FIG. 9.
